Description

Technical Field

[0001] This application relates to the field of industrial furnace technology, and in particular to an industrial furnace opening sealing device. Background Technology

[0002] An industrial furnace is a thermal device used in industrial production to heat materials or workpieces using heat generated from fuel combustion or electrical energy conversion. During the operation of an industrial furnace, materials need to be frequently fed into the furnace, requiring frequent opening and closing of the furnace door. Most existing industrial furnaces require manual opening and closing, which is inconvenient. Therefore, a furnace opening sealing device for industrial furnaces is proposed. Utility Model Content

[0003] To address the inconvenience of manually opening and closing most existing industrial furnaces, this application provides an industrial furnace opening sealing device.

[0005] An industrial furnace opening sealing device includes a workbench. A furnace chamber is fixedly installed on one side of the upper surface of the workbench. Two sets of furnace doors are provided at the inlet of the furnace chamber. The two sets of furnace doors are rotatably connected to the furnace chamber on opposite sides by rotating columns. The lower ends of the rotating columns extend to the bottom of the workbench surface and are provided with rotating mechanisms. The rotating mechanisms are used to close or open the furnace doors. A conveying mechanism is provided on the upper surface of the workbench for conveying materials into the furnace chamber.

[0006] Preferably, the conveying mechanism includes a pallet, with rollers rotatably mounted at the four corners of the lower surface of the pallet. Slide grooves are provided on both sides of the upper surface of the worktable, with the rollers located inside the slide grooves on the same side. A transfer box is provided on the upper surface of the pallet, and the side of the transfer box closest to the furnace chamber is rotatably connected to the pallet via a rotating shaft. The slide grooves are arranged along the furnace chamber inlet direction, and the axis of the rollers is perpendicular to the slide grooves.

[0007] Preferably, a limiting rod is inserted into one side of the pallet, and a limiting groove is formed on the upper surface of the worktable away from the furnace chamber, with the limiting rod and the limiting groove being inserted into each other.

[0008] Preferably, each of the rotating mechanisms includes a gear fixedly installed at the lower end of the rotating column, a torsion spring sleeved on the outer surface of each rotating column, one end of the torsion spring being fixedly connected to the worktable, and the other end of the torsion spring being fixedly connected to the gear. Both sets of gears have toothed plates meshing with them on their outer sides, a connecting frame being fixedly connected to one end of each set of toothed plates, and a movable plate being fixedly connected to one end of the connecting frame. A movable groove is provided on the upper surface of the worktable, and the movable plate extends above the worktable through the movable groove. A spring is fixedly connected between the movable plate and the inner surface of the movable groove.

[0009] Preferably, when the limiting rod is located inside the limiting groove, both the spring and the torsion spring undergo elastic deformation, and the furnace door is in a closed state.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] This utility model, by setting a rotating mechanism, can automatically open and close the furnace door. When the furnace door is open, the user can transport materials into the furnace chamber through the conveying mechanism. After the conveying is completed, the rotating mechanism can automatically close the furnace door.

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0019] This application discloses an industrial furnace opening sealing device, including a workbench 1. A furnace chamber 2 is fixedly installed on one side of the upper surface of the workbench 1. Two sets of furnace doors 3 are provided at the inlet of the furnace chamber 2. The two sets of furnace doors 3 are rotatably connected to the furnace chamber 2 on opposite sides by means of rotating columns 14. The lower ends of the rotating columns 14 extend to the bottom of the workbench 1 and are provided with rotating mechanisms. The rotating mechanisms are used to close or open the furnace doors 3. A conveying mechanism is provided on the upper surface of the workbench 1 for conveying materials into the furnace chamber 2.

[0020] In this embodiment, by setting a rotating mechanism, the furnace door 3 can be opened and closed automatically. When the furnace door 3 is open, the user transports the material into the furnace chamber 2 through the conveying mechanism. After the material is transported, the rotating mechanism can automatically close the furnace door 3. Therefore, this application does not require the user to manually open and close the furnace door 3, which is convenient to use.

[0021] Furthermore, the conveying mechanism includes a pallet 5, with rollers 10 rotatably installed at the four corners of the lower surface of the pallet 5. Slide grooves 4 are provided on both sides of the upper surface of the workbench 1, with the rollers 10 located inside the slide grooves 4 on the same side. A transfer box 8 is provided on the upper surface of the pallet 5, and the side of the transfer box 8 closest to the furnace chamber 2 is rotatably connected to the pallet 5 by a rotating shaft 9. The slide grooves 4 are arranged along the inlet direction of the furnace chamber 2, and the axis of the rollers 10 is perpendicular to the slide grooves 4.

[0022] Furthermore, a limiting rod 11 is inserted into one side of the pallet 5, and a limiting groove 12 is opened on the upper surface of the workbench 1 away from the furnace chamber 2, with the limiting rod 11 and the limiting groove 12 being inserted and engaged.

[0023] In this embodiment, when material conveying is not required, the limiting rod 11 is inserted into the limiting groove 12, which can limit the mechanism such as the pallet 5 and the roller 10, and prevent the roller 10 from moving along the slide 4. When material conveying is required, the limiting rod 11 is pulled out from the limiting groove 12, and the material is placed inside the transfer box 8. The side of the transfer box 8 facing the furnace chamber 2 is set as an opening. The user pushes the pallet 5, so that the roller 10 rotates along the slide 4 until the opening side of the transfer box 8 moves into the furnace chamber 2. Then the side of the transfer box 8 located outside the furnace chamber 2 is lifted upward, and the transfer box 8 rotates upward around the rotating shaft 9. The transfer box 8 becomes inclined, and the material in the transfer box 8 can slide down the inclined surface into the furnace chamber 2.

[0024] Furthermore, the rotating mechanism includes gears 13 fixedly installed at the lower end of the rotating column 14. Torsion springs 15 are fitted on the outer surface of the rotating column 14. One end of the torsion spring 15 is fixedly connected to the worktable 1, and the other end of the torsion spring 15 is fixedly connected to the gear 13. Tooth plates 16 that mesh with the gears 13 are provided on the outer side of both sets of gears 13. A connecting frame 7 is fixedly connected to one end of the two sets of tooth plates 16. A moving plate 6 is fixedly connected to one end of the connecting frame 7. A moving groove 17 is opened on the upper surface of the worktable 1. The moving plate 6 extends to the top of the worktable 1 through the moving groove 17. A spring 18 is fixedly connected between the moving plate 6 and the inner surface of the moving groove 17.

[0025] Furthermore, when the limiting rod 11 is inside the limiting groove 12, both the spring 18 and the torsion spring 15 undergo elastic deformation, and the furnace door 3 is closed. When transporting materials, the limiting rod 11 is pulled out from inside the limiting groove 12. When the user pushes the pallet 5 to move, the elastically deformed spring 18 and the torsion spring 15 return to their original positions, causing the moving plate 6, the connecting frame 7, and the toothed plate 16 to move. The gear 13 and the rotating column 14 then rotate, causing the furnace door 3 to rotate and open, so that the pallet 5 and the transfer box 8 can move into the furnace chamber 2.
